To all whom it may concern:

y Be it known that We, @Hannes G. Boo'rH and linens;A Sanne, both citizens of the United States, residing at Pomona, in the county of Los Angeles and State of Cali foi-nia, have invented new and useful. 1mprovelnents in Vehicle-Springs, of which the `following is a specification.

Thisinvention .relates to vehicle springs,

rlncipal ob]ect is to provide: a ve- It is also an object to provide a vehicle spring formed of a plurality of coiled spring members. n v

It is also an object to provide a vehicle spring in which the resilient members are protected from the Weather and llocated in horizontal relation in connection with the vehicle frame.

It is a further object to provide means for slidably mounting the connections from the vehicle axle and the springs togetherV with means for supporting abumper in connection with the forward springs applied to a vehicle.

In the drawings accompanying this specication and forming therewith the applieaf tion for Letters Patent: F igure-1 shows an application of the device to the forward frame of a motor vehicle. F ig. 2 is an enlarged detail in side elevation of the spring, a portion being broken away. Fig. 3 is a cross section on the line 3-,3 of Fig. 2, viewed in the direction indicated by the arrows.

More specifically in the drawings, 5 designates one of the longitudinal side frames of an automobile of the channeled type, to which is secured the axle 6 of the common cross sectional construction, the resilient 'support therefor being shown as an improved spring and shock absorber 7. Prie mal-ily this combined spring and shock ab'- sorber consists of a supporting member 8 shown as a channeled structure secured to the frame 5 by means of bolts 9 in such po- .,Vsition that the flanges extend downwardly `Iand are spaced apart to form a guide Way Specification of Letters Eatent.

through adapted to carry a hinge pin 19 which is supported in bores in the lugs 20, a pair of these being formed on either side oi the axle plate 21. rlhis plat-e is secured to the flanges of the axle 6 by bolts 22.

Secured to the outside of the yokes 17 and the armslS are rollers 2li one on either side which are adapted to travel in the longitudinally disposed slots of the depending iianges of the member 8, the rollers being held inv position by means of nuts 25 secured to either end of theaxle 16.,-

The spring 11 previously mentioned is of less length and tension than the spring 10 and is adapted to be interposed between the hub 15 and the `slotted stop 26, this slotted stop being secured in proper relation .to the member 8 by means of fastenings 27. vThe spring 10 bears on the other side oi this slotted stop and the outer end of the spring rod 12 is threaded and provided with a nut 29 and washer 30' so that the tension of the springs 10 and 11 may be adjusted to suit individual requirements or take up for loss of tension due to use. -A

As previously stated, the forward spring rod 12 is provided with extensions and With this exception the other part of the component spring is exactly similar to that described and will receive the same designation numbers, the extension 14 being provided of such length as to extend beyond the end of the frame 5 and the member 8 such a distance as to form a support for the bumper 32, a Flange 33'being formedV on the rod acting as a stop to receive the thrust and the forward plate of the bumper of the usual configuration being secured by any desired means. I

In assembling the springs on the rod they may be placed in position with the rod pivoted from the outer end of the slot,` but when placed Within the housing the bolt 35 pivotally secured to the -free ends of said pair of pivoted arms, saidrods being recip;

rocally mounted on said vehicle frame,

' springs mounted en each of said springrods,

and a stop mounted on each of said spring rods and rigidly secured to said vehicle frame, said stops being interposed between the springs on said rods, whereby resiliency is imparted to the axle through the medium of the pivoted arms.

2. In combination with a frame and Wheel.

axle of a vehicle, of' a channeled body member secured thereto having slotted fianges depending below said frame and intermediate saidA axle and frame, pivoted arms secured to said axle and extending intermediate of the slotted flanges of said body,

spring rods slidably supported Within saidA flanges, roller means engaging said flanges to support said rods, means to connect said arms to said-rods, a plurality of springs 'adapted to encircle said rods, and means interposed between each pair of springs on .said rods to act as a stop therefor.

'3. In combination With a frame and Wheel axle of' a vehicle, of a' channeled body member secured thereto having slotted `flanges depending below said -frame and intermediate said axle and frame, pivoted arms secured to said axle and extending intermediate of the slotted flanges of said body,

spring rods slidably supported Within said Hanges, roller means engaging said flanges to support said rods, means to connect said arms to said rods, a plurality of springs adapted to encircle each of said rods, slotted stops interposed between said springs, ad-
